FS-85 Application

  • FS-85 belongs to niobium high temperature alloy, which is widely used in aerospace industry. It can be used as a structural material for the shuttle engine, a rocket nozzle and a hot exchange pipe for a jet plane.

  • FS-85 is a high strength niobium alloy. With niobium as the base metal and adding a large amount of tungsten, molybdenum, titanium, zirconium and other metal elements and a small amount of carbon element, this niobium alloy has high solid solution strengthening, combined with C precipitation strengthening. This kind of alloy has high tensile strength, creep strength and fatigue strength in the 1300-1600˚C range.
